IncorrectQuestion 1
pts
A researcher is studying the effect of hypnosis on pain experienced during
dental procedures. The researcher’s study has two groups: those who receive
hypnosis during the procedure and those who receive no hypnosis. If the
researcher plans to use a t-test for the statistical analysis, which would be
the best way to measure pain for this study?
pain scale where the participants report their pain as: none, some, intense
patient report of presence or absence of pain
numerical pain scale with a range from 0 to 100
p.411
Question 2
pts
A researcher performs a series of pilot studies to evaluate whether a
measurement tool produces consistent results. This is an evaluation of:
Reliability
Accuracy
Readability
Validity

Question 3
pts
A researcher develops a 7-point Likert scale to evaluate feelings of well-being
in patients who are undergoing chemotherapy. The researcher administers
this measure to other, similar patients in several medical centers. This is
done in order to:
increase interrater reliability
, strengthen the operational definition of the constructs
improve the test-retest reliability
Decrease mono-operation bias

Question 4
pts
In a pilot study to help train a group of data collectors who will evaluate
children’s pain using a FACES rating scale, the researcher examines the
reliability of the scores of each data collector. This is an example of which
type of reliability measure?
Test-retest reliability
Internal consistency reliability
Interrater reliability
alternate forms reliability

Question 5
pts
A researcher evaluates scores of a paper and pencil instrument with
variables at the interval level of data using the Cronbach’s alpha coefficient
statistical procedure. This is a test of:
interrater reliability
test-retest reliability
alternate forms reliability
